This invention relates to a marker unit designed primarily for marking oif cours-esfor pedestrians at street intersections and crossways, but it isy to be understood that a mark- 5 er unit in accordance with this invention may be employed in any connection for,

which it may be found applicable, andthe invention hasl for its objectto provide, in a manner as hereinafter set forth, a marker unit including a combined marker and anchoring element and a spreader element,and with said elements coacting and constructed in a manner relative to each other tok provide for the secure anchorag-e of the marker unit when the latter is arranged in marking position. Y v A further object of the invention is to provide, in a manner as hereinafter set forth aV up with a bright outer surface and as such surfacescars'or wears away, the same brightness and other characteristics thereof remain as there isno plating or covering to wear 3 5 completely away. Under such conditions the 'hea'd,on continued use down to the last l/l6 of an inch thereof will give the same'eifect as the effect given on the installation 'ofthe aforesaid element.

40 VAfurther object ofthe invention is to` provide', in a manner as hereinafter set forth, afmarker unit vincluding a combined marker and anchoringelement having afone-piece, non-coated or non-covered head possessing the ycharacteristics to provide a hard wearing surface that will stand considerable abuse, automatically polish itself under con- Y tinued use as it is worn away and further overcome; the disadvantages possessed by a lMonel metal head covering. as such covering yrender it' rustV resisting andV to give it, during wears away exposing a dark head, is crimped to the head when positioned on the latter, and wears at its edges resulting in the covering becoming separated fromthe head.V

Further objects o f lthe invention are to provide, in a manner` as hereinafter set forth, a marker unit for the purpose referred to and which is simple in its construction and arrangement, strong, durable, compact, thoroughly` efficient in its use, readily installed and anchored ini marking position, quickly assembled and comparatively inexpensive to manufacture.

With the foregoing and other objects in view, the invention consists of the novel construction, combination and `arrangement of parts as hereinafter moreA specifically described and illustrated in the accompanying Ydrawing wherein is shown an embodiment of the invention, but it is to beunderstood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended.

rI he elements are formed from such .metals or alloys of metalsto providea unit which doesnotrequire plating or afl covering to continued use brightness suiicient to make it readily applicable for the useage for which the unit is designed.

The element 1 includes a circular head 2 of segmental cross section. `The head 2 has a curved outer face 3. The inner face of the head 2 is formed with a central, circular flat portion 4, an annular flat portion 5 aligning with the portion 4 and an annular groove 6 of arcuate cross section separating the flat portions 4, 5. Although the head is illustrated as of circular form, yet such contour is shown by way of example, as the head can be of any desirable contour other than that shown.

' y,The element 1 further includes a stem formed of three spaced arms 7, 8 and 9 which are integral at their outer ends with the portion 4 ofv the inner face of the head. Each arm has its outer end disposed at an angle with Arespect to the portion 4. The integral outer ends of the arms are angularly disposed with respect to each other and in a manner whereby the stem in lcrosssection will be of triangular contour. Each arm isl of oblong form. rThe inner end of each arm is free and indicated at 9 The end 9 is squared. VvThe side edges of each arm are oppositely beveled'. The arms are spaced equal'V distance from each other. The length of the arms is greater than the vdiameter ofthe head. The arms provide anchoring members for the lelement 1 lwhen the unit isset in marking position. The' major part of the outer ends of the arms is spaced inwardly from the edge of portion 4. The head yand arms are formed of like material. Thearms are of the desired thickness. The arms when in anchored positionl have the inner portions thereof flared outwardly with respect to each other and with respect to the axis of the head of element 1.

Thespreader element 2 in cross section is of sexagonal contour. VThe length offelement 2 is slightly lessthan' the length of the; anchoringmembers providedbythe arms 6, 7 and81f The element 2 includes a base 10 and 'an' upstanding tapered 'spreader member 11.

The base includes `the sides12, 13, 14, 15, 16 and 17. The sides 12,14 and 16 are of less width than the sides 13, 15 and 17. The

upper face of base 10 is downwardly'beveled towards the sides 12, 13, 14, 15, 16 and 17 as at`18, 19, 20, 21, 22 and 23 respectively. The member 11 at its lower end is integral .with the upper face and'is inset with respect to the sides of the base 10. The beveled parts 18,19, 20, 21, 22 and 23 of the base 10 extend from the lower end of the" member 11 to the sides of base 10A andthe parts 19, 21 and'23 constitute deflecting surfaces for theV arms 6, 7 and 68.,"` The parts 18, 20, and 22 are of less widththan parts 19, 21 and 23.

-The member 11 is vformed with sides 24, 25, 26. 27. 28' and 29 and such sides incline inwardly from their lower to their upper ends. Each side of member 11 gradually decreases in width from its lower to its upper end. The sides 24, 26 and 28 of member 11 are of less width than the sides 25, 27 and 29. The sides 24, 25, 26, 27, 28 and 29 of member 11, at their lower ends merge into thebeveled parts 18, 19, 20, 21, 22 and 23 respectively. The sides 25, 27 and 29 constitute spreading surfaces for` the arms 6, 7 and 8.

The arms 6, 7 and 8 of the stem are disposed at acute angles with respect to each other. r1 his provides a passage 30 for member 1() of element 2. The openings 31 between the side edges of the arms 6, 7 and 8.are 120 degrees apart.

It Will be assumed, by way of example, that the unit is to be anchored in a V8 hole in the concrete. and anchoring element would measure 7/3 of an inch at three points and this wouldbe sufficient to anchor the marker in a' hole,A or 4socket of the dimensions' referred to'. y The base of the spreader element would be' of slightly less dimensions than thatof' the stem. The spreader element is mountedy in the hole vor socket, after which the stem of element 1 is mounted on elements 2, as the element 1 is The stem of the combinedmarker.

forced inwardly, the arms V6, 7 and 8 will spread relative to member 11 due to the action of sides 25, 27 and 29. l/Vhen the squared ends of the arms reach the beveled parts 19, 21 and 23 of base 10 the ends of the arms-will be deflected and the arms can pass base 10 until the upper end of member 11 abuts portion 4of the head 2. This action crowds the arms 6, 7 and 8 inthe wall ofthe hole or socket at three points and securely anchors The element 1 is forced inwardly until the' Vhead bears the unit in marking position.

against the surface in which the hole'or'socket .is formed. Y v

It is thought that the many advantages 'of a marker unit, in accordance with this invenftion canbe readily understood, and although the preferred embodiment of the"inventi'o'n is as illustrated and described', it is to be understood-however, that changes in the de'- tails of construction can be had which fall vwithin thev scope of the invention as claimed. l/Vhat I claim is ze' 1.
